SPECIFICATION forming part of Letters Patent No. 721,757, dated March 3, 1903.

- Application filed May 26,1902. Serial No. 108,966. (No model.)

To aZZ whom it may concern.-

Be it known that I, JASPER N. TABLER, a citizen of the United States, residing at Royse City, in the county of Rockwall and'St-ate of Texas, have invented certain new and useful Improvements in Safety-Envelops;;and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates toenvelops, and particularly to that class in which the contents are rendered secure by making it impossible to remove the same Without mutilation and detection.

The objects of my invention are to provide an envelop of this character which shall be simple of construction, cheap to manufacture, durable in use, and free from the liability of being opened without detection. I accomplish these and other objects, which will appear as the nature of the invention is better understood, by means of the construction illustrated in the accompanying drawings, in which- Figure 1 is a plan of the inside of the blank from which my improved envelop is made. Fig. 2 is a similar view of the outside or reverse side. Fig. 3 is a plan of the backface of the envelop before the sealing-flap is inserted in the pocket. Fig. 4 is a section on the line 3 3 of Fig. 3. Fig. 5 is a similar section after the sealing-flap has been inserted in the pocket and the envelop sealed.

My invention consists in providing an en'- velop of well-known construction, consisting of a front and rear face,'two end flaps, and the usual sealing-flap, with a sealing-pocket for the sealing-flap, in which said sealing-flap is inserted and sealed to one of the interior surfaces of the pocket, and then the other intorior surface of the pocket, which is also gummed, is sealed upon the top flap,making a double seal for the envelop. I

In the drawings, 1 denotes the part of the blank which forms the back or rear face of the envelop, and 2 the portion which forms the front or face, on each end of which are the usual end flaps 3 and 4. The usual gummed sealing-flap 5 is formed on the top edge of the face portion 2 and has a row of perforations 6 around its outer edge for the of the back portion 1, opposite the face portion 2, is the flap or portion 7 ,which is folded upon itself to form the sealing-pocket which receives the sealing-flap 5. The said flap 7 consists of the two portions or members 8 and 9, which, as stated, are folded together to form the pocket between them. The member 8 is gummed on both sides, as shown at a and b.

In making or forming my envelop the end flaps 3 and 4 are first folded in upon the inside surface of the front portion 2, and the back portion 1 is then folded up upon the flaps 3 and 4. The gummed portions 10 of the inside surface of the back 1 are moistened and adhere to the flaps 3 and 4. The flap 7 is now folded upon itself to form the pocket, which is theninserted in the envelop, as shown in Fig. 4. The gummed surface of the portion 8, which is on the outside of the pocket, is moistened before the pocket is turned into the envelop, and after it is folded in this surface will adhere to the end flaps 3 and 4 and the back portion 1 and greatly strengthen these parts.

In the sealing of the envelop after the contents have been inserted the gummed sealingfiap 5 is moistened and folded into the pocket formed by the portions 8. and 9, and this gummed surface of the flap 5 will adhere to the inner surface of the portion 9 of the pocket. The gummed surface of the portion 8, which is on the inside of the pocket, is then moistened and pressed against the flap 5, to which it will adhere and securely seal it in place. By this construction it will be noticed that the envelop is securely closed by the double sealing of the flap 5, which cannot be removed from the pocket without noticeable damage being done to the flap and pocket. Another advantage is the'smooth back and neat appearance derived from this constructiomenabling me to use the back of the envelop for an advertisement, if desired.

From the foregoing description, taken in connection with the accompanying drawings, it is thought that the construction, mode of operation, and advantages of my improved safety-envelop will be readily apparent without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention,and any suitable materials may be used in the manufacture of the envelop.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a safety envelop, the combination of front and back portions, the front portion being provided with end flaps and a perforated gummed sealing-flap, the back portion having a gummed surface and being provided JASPER N. TABLER.
